The Schedule referred to in these Letters Patent and making part of the same.`

.To all whom it may concern: A

London, in the ,county of 'Huron, and State of Ohio,

" have invented certain new and useful Improvements in Brick-Machinesg and I do herebydeclare` that the `following is a full and complete `description of the same,

reference beinghad to the accompanying drawings,

making part of this specification, in which- Figure 1 is a front viewof the machine. Figure 2, a view of the top. Figure 3, a view ofthe bottom.

Figure 4, a transverse veltical section.

Like letters of reference refer to like parts in the differentviews presented.

This invention relates toa machine for making bricks, by means of which the clay is forced into the moulds directly from the mill by a cam, which, operates on the end of the shaft towhich the follower of the press is attached, atthe same time delivering the filled moulds successively, one after the other, at the front of the machine, as hereinafter more'fully de.

scribed. V y

In fig. 1 l Arepresentsthe case, into which the crude clay is thrown, for being reduced to proper consistence for moulding, the reduction of the claybeing eifectedyby theiarms B, g. 7, radiating fromthe shaft G, iig. 4, the same being operated oy-the sweeps D, to which animal, or other power may be applied.

Efg. 1, is the box or die of the` press, in which is fitted a follower, F. Said follower is attached tothe lower end of the shaft G, andsecured to the side of the caseby meansof guide-staysH, in which it moves upward and downward, by means of the earn-wheel I, with which the upper end is put in connection, by means ofthe friction-roller (t, ahovethe uppensideof the wheel and the frictionroller l, ou the under side, as shown in fig. 4 p, l

rlhe cam-wheel referred to is so constructed that two of its opposite sides J, are elevated' above 'an equatorial line, c, whereas the other two opposite sides Karo belowv said line, thereby forming cam-like ele- `rations and depressions, whereby the follower is operated, as will presently be shown. y

The device for removing the filled Inoulds from under the press is as follows: Y

'It will be observed that the shaft C descends through the bottom of the case, thence through the space L, through the vtable M, into the space below the machine. f

From the projecting end of the shaft proceed radial arms N, fig. 4, which, as the shaft is made to revolve, impinge upon the arm O, projecting upward from therock-shaft P.`

At the opposite end of said shaft is an arm, Q, which, together with the arm 0, passes up through the mouldsR, and whereby the moulds are pushed from under the press, on to the frontend of the 4table M.

Having tlus described the construction and arrangement of the press, the practical operation of the same is as follows, viz:

As above said, the crude clay Iis put into the case or mill A, and therein reduced to a proper consistency for being pressed intothe moulds.

The first set of moulds is brought into positionfor receiving the clay` by pushing them under the pressbox from the front. 'lhe follower ofthe press being elevated by the cam J of the wheel, as shown in iig. 1, theinncr side of the press-box thereby becomes open to the mill, and from which the plastic clay is forcedout'into the press, and into the mould R, through the throat or opening A', by meansof the revolving radial -ing upon the roller b,.of the shafts Gr.

The amount of pressure thus exerted upon the followerV by the cams of the wheel is sufficient only to cause rthe clay to properly fill themoulds; hence, no great power is required to operate the press.' The filled mould is removed fromunder the press by the introduction of ase-cond one, and which is done by inserting one end vof the mould in the opening G, Ag. 4, in the rear of the filled mould It, which, as the shaft G revolvesthe arms N, impinge upon and push for ward the arm O, thereby forcing the bar a, whereby the two arms O and Q are connected, against the rear side of the empty mould, driving it forward `against the filled mould It, and crowding it from under the press on to the table in frontof the machine, as shown in fig. 2, the length of the arms O andQ bein'g such as to carry the empty mould immediately vunder the press'.

It will be observed that the pressure is applied to the mould, and the `same forced o'ut from under the press Vduring the time that the roller a is passing over the face of the cam K, lthe empty mould being .pushed into position at the time that the mould under the press is filling, or while the follower is'raised up, and continued thus raised up during the time thatthe roller 'c travels over the face of the cam J. Hence, as fastas one sctof moulds is filled, it is followed and pushed from under the press by a'second, thereby filling two sets of moulds, and delivering them at the front of the machine, at each revolution of the wheel, and so on, as long as the wheel continues to. revolve, a succession of illedmoulds is presented on the table, in front of the press. Each time that the arms O'and Q have been pressed forward by the arm or sweep N, for discharging the moulds from under the press, they ure returned by the reaction of the spring D', in time to be again driven forward by lche erm or sweep N.

The mill muy be -nsed independently of Jche press,

for the purpose of reducing the clay to a proper com sisteney for moulding, by withdrawing the piu f, fig. il, thereby allowing' the leyer F', pivoted to the side of the ease, to drop, as indicated by the dotted line h, und thus prevent' the sweep N from engaging tlieurm 0, but; which will revolve freely thereof', above the shoulder of the erin. i

The front side of the press, as seen al; E", fig. l, is so fitted to the press or box mthetitreen move upward, :is indicated by the dotted line u, iig. l, the purpose .of which is, that on pushing the set of moulds R from under the press,should a stone or other like obstruction present itself above the surface of the mould, it could not slide ont', unless su'eh obstruction be removed, or the front of the press or box be forced upward by Ialle obst1l1otion,which lutter 'will be the ease, and thus allow the lmould to come forth, which, on being done, the side is again forced down to the position sl'lowl by the spring- G, for scraping the surface ofthe mould.

What l claim as iuyimprovement, and desire to secure by Letters Pai-tent, is-

l. The adjustable side E und spring G', ns arranged in eombinationwibh t-he press-box E, in the manner as und for the purpose set; forth.

2. The rock-shaft; P, arms O Q, and spring' D,\vhen constructed und arranged to operate by menus of the sweep N, in the manner as described, and for the purpose speoiiied. Y
